1 Claim.

This invention relates to register grilles, and more particularly togrilles of registers forming a part of heating systems, ventilatingsystems or the like.

The primary object of the invention is to provide a grille wherein theair passing therethrough, will be divided and directed in oppositedirections, insuring a more even distribution of the air in conditioningthe air of a room.

Another object of the invention is to provide a grille of this characterwherein the blades of the grille are divided into groups, the blades ofeach group being so connected that when the operating lever is moved toadjust the blades, the blades of the groups will be tilted in oppositedirections, simultaneously.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claim, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

Referring to the drawing Figure 1 is a plan view of a registerconstructed in accordance with the invention.

Figure 2 is a side elevational view of the register, a portion of one ofthe side bars having been cut away, illustrating the ends of the blades.

Figure 3 is a sectional view taken on line 3-3 of Fig. 1.

Figure 4 is a fragmental perspective view, a portion of one of the sidebars having been broken away, illustrating the connection between thegrille blades and operating bars.

Referring to the drawing in detail, the register comprises a rectangularframe 5 constructed of channel bar material, the open sides of thechannel bars being disposed downwardly, as clearly shown by the drawing.

Supported by the frame, are grille blades 6 which have reduced ends 1extended at right angles with respect to the blades proper, providingarms to pivotally connect the grille blades to the inner surfaces of theside members of the frame. Extending laterally from the free end of eachreduced end or element 1, is a pin 8, which pins provide means forpivotally connecting the reduced ends I of the grille blades, with theoperating bars 9 that are supported within the open sides of the sidemembers of the frame. As shown, the grille blades are arranged ingroups,

and the blades of each group are connected with.

an operating bar 9. The adjacent inner ends 01' the operating bars 9 arespaced apart, so that they may move towards or away from each other,during the operation of the grille blades.

Dividing the grille frame, at a point intermediate its ends, is a barII) which has downwardly extending ends II that are secured to the sidemembers of the frame by means of the bolt l2 which bolt also provides apivot for the bearing l3 of the operating lever [4 that extends upwardlythrough the elongated opening l5 formed in the upper surface of theangle bar forming one side of the frame. The operating bar 9 at one sideof the frame, has its inner end pivotally connected with theoperating'lever [4, at l6, or at a point below the bolt I2, while theopposite operating bar 9 has pivotal connection with the link l1 whichalso has pivotal connection with the operating lever I4, at a pointabove the bolt l2.

Thus it will be seen'that due to this construction, when the operatinglever is moved to the right or left, the grille blades will be moved sothat the blades of opposite groups are disposed at acute angles withrespect to the upper edg of the grille frame, the blades of the groupsbeing disposed in opposite directions.

Due to this construction, it will be seen that the blades providedeflecting plates to direct the air or heat passing through theregister, in opposite directions, at opposite ends of the grilleregister, thereby distributing the air evenly throughout the entire areaof the room.

What is claimed is:

A register of the class described, comprising a rectangular frameembodying wide side and end channel bars having their open sidesdisposed downwardly, the inner legs of the channel bars being shorterthan the outer legs thereof, groups of wide grille blades havingdownwardly extending ends, pivotally connected to the inner legs of thechannel bars, pivot pins secured to the free ends of the downwardlyextended ends of the blades and being extended outwardly into thechannel spaces of the side channel bars below the lower edges of theinner legs of the channel bars, a horizontal operating bar connectedwith the pivot pins of the blades of each group of blades, an operatinglever pivotally mounted within the channel bar space at one side of theframe, the channel bar in which the operating lever is mounted having anopening through which the lever extends, the lever being pivotallymounted at a point intermediate the ends of the channel bar, means forpivotally connecting one end of the horizontal operating bar of onegroup of blades to the operating lever at a point below the pivot of theoperating lever, and a link pivotally connected to the operating bar ofthe opposite group of grille blades, said link being pivotally connectedwith the-operating lever at a point above the pivot point thereof,whereby movement of the operating lever in one direction, simultaneouslymoves the groups of grille blades in opposite directions.
